This chapter only applies to unpassed-hand responses!
Twisted 2/1 inspired me to swap suits of 2/1 responses. I swap 2♣♥
rather than rotate 2♣♦♥ for mundane reasons:
- Partially natural 2♦ suffers fewer lead-directing doubles.
- Bidding 2♦ with both minor suits feels better.
Especially, the 2♣ response helps us make more 4♥ and 2♥ contracts than natural
methods.

Note that 2♦ is also in charge of the constructive raise.
